1. Product introduction



Rigidity refers to the ability to resist elastic and plastic deformation when subjected to force. Rigidity is mainly determined by hardness, tensile modulus, flexural strength and flexural modulus. Rigidity is one of the structural properties of tablets.



Drug tablet is a wide range of dosage forms of traditional Chinese medicine in clinical application. Due to its complex prescription composition, hard texture and structure, drug rigidity, a series of processes are closely related to the microstructure and mechanical properties of drugs in the production and processing of drug pressing, molding and coating, drug transportation and storage, as well as the disintegration, dissolution or release and curative effect of formed tablets in human body. The microstructure and mechanical properties of drugs can be comprehensively expressed as drug rigidity, and its data can be characterized by the texture characteristics of drugs. Bowman drug rigidity tester can objectively measure the hardness and strength of tablets and affect the drug release effect.



2. Brief introduction of Baoman drug rigidity tester



Through the test and comprehensive analysis of the stress and strain of the tablet, such as puncture, compression, shear and tension, the Baoman drug rigidity tester can obtain the indicators of tablet penetration strength, tablet rupture strength, tablet brittleness, tablet stability, tablet decomposition degree and tablet disintegration rate, which can comprehensively guide the formulation, process design and drug release mechanism of the tablet.



Bowman drug rigidity tester is a professional physical property analyzer used in the pharmaceutical industry. It can objectively evaluate the mechanical properties of drugs and give an accurate quantitative description of the mechanical index results. Avoiding the limitations of human sensory evaluation, we can get accurate, stable and reproducible physical parameters of different samples. Such as: tablet hardness, tablet firmness, elasticity, toughness, tablet fragility, chewiness, adhesion and adhesion. When the sample is subjected to static or dynamic force, it will be accompanied by the change of pressure or deformation force.



3. Application and performance characteristics of Bowman drug rigidity tester



1. Application: used for drug testing, penetration strength, skin hardness and rupture strength of tablets. The instrument can record the stress changes in the process of tablet crushing, and can also obtain the initial modulus and rupture work value, providing more comprehensive information of sample rupture;



2. Instrument parameters: display accuracy of test results: 0.01g; Displacement accuracy: 0.01mm; Moving distance of test arm: 280mm; Detection speed: 0.01 ~ 25 mm / S; Data acquisition rate: no less than 500 groups / s, and 4 channels in each group are read at the same time;



3. The third-party weight with high precision can be used to verify that the force conforms to the ASTM E7500 standard, and the third-party weight can be used to calibrate the force;



4. High precision force sensing element, 0-100kg, 500g, 1kg, 5kg, 20kg, 30kg, 50kg and 100kg can be selected;



5. The equipment adopts three-axis ball screw, which has stable structure and is not easy to change. The stepping motor at the bottom is designed with accurate and stable displacement, no resonance and no noise;



6. One measurement, automatic calculation of multiple test indicators, eliminating the cumbersome calculation process;



7. Result analysis: automatically analyze the result of the curve. Users only need to select the desired result according to their own needs. At the same time, the curves and results can be transmitted to the computer for backup. It can export pictures, Excel, PDF, original data and other functions with one click, and can quickly analyze and process hundreds of groups of data at the same time. The data can be opened by office software. It has the function of confidentiality of detection data;



8. After sales service requirements: the instrument shall be guaranteed for 1 year free, installed and debugged free of charge, and free video training shall be provided for the operation, repair and maintenance of the purchaser's technicians until they can operate skillfully and independently and maintain for life;



9. Configuration: Baoman drug rigidity tester host, Ta / 2, spare parts package, a set of external software, application method library and operation manual.
